Abstract
We report recent progress in the construction of a new aberration-corrected photoemission electron microscope. The correction element in this instrument is a hyperbolic electron mirror, correcting for chromatic and spherical aberration. We present results from a numerical simulation combining a trajectory and wave-optical analysis, and we discuss the calculation of the modulation transfer function in this approach. First images on nano-structured metal and semiconductor surfaces have been obtained with the new instrument and are also presented.
